Get the x-factor at your practice
The DALE Foundation’s DANB RHS Review course covers important topics related to both conventional and digital radiography and is a great way to prepare for the DANB Radiation Health and Safety (RHS) exam.
The DANB RHS Review course is an interactive online learning experience broken down into 13 course modules. You may take one subject at a time or all 13 at once – how you divvy up completing the course within your six-month access period is totally up to you. Before, during and after the course, you will complete learner assessments, so you can continually check your progress. You may also go back and review any part of the course at any time, and retake your post-course assessment* to make sure you are ready for DANB’s RHS exam.
*Questions are not from actual DANB exams, and completing the review course does not guarantee that you will pass the DANB RHS exam. Course credentials
